【摘要】 在车用汽油机的各种稳态工况下测量了不同初始点火提前角和空燃比条件下运行时的汽油机废气中碳氢（ＨＣ） 化合物、一氧化碳（ＣＯ） 、氮氧化合物（ＮＯｘ） 的排放特性，由实验结果分析了各种运转参数对汽油机废气排放特性的影响关系，为综合匹配各运转参数来达到降低车用汽油机污染物排放量奠定了基础。更多还原

【Abstract】 Correlation of emission maps with spark timing and A/F ratio from an automotive S.I. gasoline engine CA6102 was studied experimentally. The characteristics of spark timing and A/F ratio effect on HC、CO and NO x emissions are analyzed through test data, these characteristics may be used to correctly select or control the spark timing and A/F ratio for decreasing the exhaust emission of a gasoline engine.更多还原
